Pseudo Euclidean-Signature Harmonic Oscillator, Quantum Field Theory and Vanishing Cosmological Constant

TL;DR

This paper explores a pseudo-Euclidean harmonic oscillator and its quantum field theory, demonstrating how a suitable vacuum definition cancels zero-point energy, leading to a zero cosmological constant and predicting stable exotic matter with negative energy.

Contribution

It introduces a method to cancel vacuum energy in quantum fields using pseudo-Euclidean metrics, offering insights into the cosmological constant problem and exotic matter predictions.

Findings

Vacuum energy cancels out in pseudo-Euclidean scalar fields.

The theory predicts stable negative energy excitations (exotic matter).

Cosmological constant is exactly zero in this framework.

Abstract

The harmonic oscillator in pseudo euclidean space is studied. A straightforward procedure reveals that although such a system may have negative energy, it is stable. In the quantized theory the vacuum state has to be suitably defined and then the zero-point energy corresponding to a positive-signature component is canceled by the one corresponding to a negative-signature component. This principle is then applied to a system of scalar fields. The metric in the space of fields is assumed to have signature (+ + + ... - - -) and it is shown that the vacuum energy, and consequently the cosmological constant, are then exactly zero. The theory also predicts the existence of stable, negative energy field excitations (the so called "exotic matter") which are sources of repulsive gravitational fields, necessary for construction of the time machines and Alcubierre's hyperfast warp drive.
